Multi-Stage Ultrasonic Cleaning System

Multi-Stage Ultrasonic Cleaning System

Whether cleaning delicate medical instruments or heavy-duty industrial components, a multi-stage ultrasonic cleaning system can dramatically improve efficiency and reduce costly scrapped or reworked parts.multi-stage ultrasonic cleaning system An ultrasonic cleaner is more than just a tank with transducers—the configuration of the generator, power output, frequency and other factors directly affect cleaning performance. Incorrectly configured ultrasonic cleaning machines deliver inconsistent results and can fail to meet validation protocols and specifications, especially in the medical device, aerospace and other high-tech industries.

To achieve a superior clean, ultrasonic parts washers must be capable of loosening contaminants and chemical bonds.multi-stage ultrasonic cleaning system Often, the addition of heat is required to accelerate this process. The addition of heat also helps disperse liquid in the tank, allowing the ultrasonic waves to better penetrate the substrate being cleaned. Multi-stage ultrasonic cleaners combine a wash, rinse and dry stage for complete contamination removal. The wash stage removes carbonized deposits, polishing compounds, blazing flux, swarf, oils and paint from metal components and assemblies. The rinse stage thoroughly flushes the components with clean water to eliminate any remaining residue from the wash cycle. The final drying stage uses recirculating hot air to quickly dry the parts for immediate handling after the cleaning process.

The heart of the ultrasonic parts cleaner is an electronic ultrasonic generator. The generator transforms AC electrical energy from a standard wall outlet to energy appropriate for energizing the ultrasonic transducers at an ultrasonic frequency. The ultrasonic generator’s piezoelectric crystal transducers then generate mechanical vibrations in the solution to create cavitation bubbles that scrub surfaces of immersed components. The ultrasonic power ratio (watts per gallon) is a critical factor in the performance of an ultrasonic cleaner machine. Many low-priced machines offer a lower ratio of watts/gallon, and this can negatively impact their cleaning effectiveness.

A high-quality, U.S.-made ultrasonic cleaner features a robust, long-life ultrasonic generator with high-efficiency piezoelectric transducers. This combination produces superior ultrasonic waves that more effectively saturate the entire ultrasonic tank volume with mechanical vibration. This results in faster cleaning times, higher levels of consistent sonic energy and optimal cavitation action. Inexpensive, foreign-made ultrasonic parts washers may feature poor quality electronic components that degrade rapidly. The combination of these poor-quality components and accelerated piezoelectric transducer decay can result in erratic ultrasonic cleaner performance over time, causing inconsistent and sub-par cleaning results. Ultimately, these low-quality ultrasonic parts washers often cost more in the long run due to higher replacement costs for the ultrasonic generator and the ultrasonic tanks.
